I don't know why I haven't thought of posting this earlier but here are some kits that might work for Class 1and 2. I'm not sure how close to scale they are and they would take some modifying to make them control line but I think they could make a really good starting point. Obviously they probably aren't the absolute best in performance compared to a MO-1 but with practice I think some of them have some potential.
